The 27-year-old singer - who gave birth to daughter Ethel last November - met Sam at Glastonbury festival in 2009 and they married at St James the Great Church in Cranham, near Stroud, in Gloucestershire last year.

Lily was obviously feeling sentimental as she tweeted a YouTube link to Tommy McLain's Before I Grow Too Old, revealing it had been her first dance at the wedding.

The Smile singer is planning a garden party at the weekend, but is thinking of calling it off because of the bad weather.
